(57) The disclosure relates to an apparatus in an adjustable creasing tool (1). The creasing
tool (1) includes two mutually co-operating creasing rollers, a male roller (2) and
a female roller (3), a gear wheel transmission with a housing (8) for operation and
mutual co-ordination of the creasing rollers (2, 3), means for adjusting the mutual
position of rotation of the two creasing rollers (2, 3), means for adjusting the position
of one of the creasing rollers along its axis of rotation, and means for adjusting
the mutual spacing between the axes of rotation (4, 5) of the creasing rollers. Each
respective shaft (4, 5) is fixedly connected to each respective gear wheel (6, 7)
in the gear wheel transmission by means of rotationally rigid, both radially and axially
limited, flexible couplings (9). These permit adjustment of the mutual positioning
of the rollers (2, 3) without the meshing relationship of the transmission (8) needing
to be affected. For adjustment of the mutual position of rotation of the rollers (2,
3), the transmission housing (8) may be restrictedly rotatably fixed in the frame
of the creasing tool (1) about one of the shafts (4, 5) of the transmission.
